At 11oo point my biggest challenge is getting good sized planets, my experience from playing high end acct tells me not to keep any planet under 200 fields because of running out of building space . So far ive made 7 of those expensive colony ships and have only got one descent sized colony out of it. Is it worth the struggle trying to find the bigger planets? yes even though its a struggle to build colony ships the end result will be worth deleting off the small colonies.
